Accointing Integration

Accointing (now part of Glassnode) is a crypto tax service popular in the German-speaking EU market (Germany, Austria, Switzerland), supports German tax legislation (Jahresfrist rule — exemption after 1 year).

}

Special Feature for German Users

Accointing correctly handles the German tax exemption rule after 1 year (Haltefrist). When exporting, it is important not to lose the timestamp — Accointing calculates the holding period itself.

// For German market: rule on staking (can extend holding period)
// With staking reward, Germany in some interpretations
// resets holding period of staked coins — need to explicitly indicate
function markStakingForGermany(tx: InternalTransaction): AccointingRow {
  return {
    ...exportToAccointingRow(tx),
    classification: tx.taxCategory === TaxCategory.STAKING_REWARD ? "staking" : "",
    // Important: Accointing understands that staking reward creates a new lot
  };
}

Accointing integration via CSV export with correct classification for EU market — 2-3 business days.
